My preview changes displays that roles/organizations will be assigned. But it displays the names of the objects to be assigned, not their display names.
On the other names, Assignment tab displays role/organizations with their display names.
So the situation is not very consistent.
We should probably find a way how to display both. Preferably the display name, then the name in parenthesis or something like that?
This is after save:
Organizations "Contractors" and "IT Administration Department" are assigned.
(The roles does not make any difference in my use case as the role has either only a name or the name == display name).
